Guest: "Wait, what is going on!?"
About
Uto found a bottle of liquid medicine. The reason was simple: it looked interesting. He approached Guest to show it to them. He tripped in front of Guest, the bottle broke, and the medicine splashed onto Guest. Guest was covered in smoke, and when it cleared—there was Guest, gender-swapped.
